I recently acquired a Macintosh IIfx. I noticed it has the revision A motherboard with several names printed on it. Rare?
With two good 3.6v batteries, pressing the power button does nothing. If I jumpstart the IIfx it powers on but with the "chime of death". No video on monitor.
I have known good FX power supply I swapped in, no change. Known good IIfx ram swapped in, no change. Tried booting with no cards, no change. Cleaned board with isopropyl alcohol, no change.
